+openEHRの参照モデルでは，多重継承を使っているところがいくつかある。すべての場合で，単一継承によるサブタイプで代替可能な関係（たとえば'is-a')ではあるが，機能の継承(たとえば'has-a')や多重継承が常に用いられることもある。参照モデルでは，rm.data_types.quantity.DV_INTERVALやrm.data_types.qualntity.date_timeクラスなどはこのような継承を使っている。
 
 There are a couple of places where multiple inheritance occurs in the openEHR reference model. In all cases, only one inheritance branch corresponds to subtyping in the substitutability (i.e. 'is-a') sense; the other branches are always 'facility'  or 'mix-in' inheritance. In the RM, classes inheriting in this way include rm.data_types.quantity.DV_INTERVAL and the rm.data_types.quantity.date_time classes. The latter inherit only interface, which has no visibility in XML-schema. For the former, the inheritance of Interval<T> by DV_INTERVAL<T> is done in the schema simply by direct inclusion, since the other branch of inheritance (of DATA_VALUE) is the one which must be visible to schema processing.
